Caraz Velcro Puzzle Mat Set of 2 Each mat is 71cm x 71cm and 4cm thick, providing peace of mind even if you fall. It's ideal for reducing noise to lower floors in apartments. I used these in addition to other Caraz mats. They are relatively clean and still in good condition. They're also great for nap spaces (*^^*) Non-formaldehyde Flame-retardant puzzle mat 2 baby mats Baby play mat Floor mat Floor heating Soundproof crawling Thick waterproof Caraz Karaz floor heating compatible Color: Light Beige
